A Phase III, Multicenter, Randomized, Open-Label Study to Evaluate the Efficacy and Safety of Atezolizumab Given in Combination With Cabozantinib Versus Cabozantinib Alone in Patients With Inoperable, Locally Advanced, or Metastatic Renal Cell Carcinoma Who Experienced Radiographic Tumor Progression During or After Immune Checkpoint Inhibitor Treatment


Condition: Carcinoma, Renal Cell

Study Type: Interventional

Clinical Trials Identifier NCT 8-digits: NCT04338269

Sponsor: Hoffmann-La Roche

Phase: Phase 3

Eligibility:

  • Age: minimum 18 Years maximum N/A
  • Gender: All

Inclusion Criteria:

  • Histologically confirmed locally advanced or metastatic clear cell or non-clear cell (papillary, chromophobe, and unclassified only) RCC. RCC with sarcomatoid features is allowed. Patients with the chromophobe subtype of non-clear cell RCC must have sarcomatoid differentiation.
  • Radiographic disease progression during or following treatment with ICI for locally advanced or metastatic RCC either in first- or second-line treatment. Patients who experienced radiographic tumor progression during or within 6 months after the last dose of adjuvant ICI are also eligible. ICI is defined by anti-PD-L1 or anti-PD1 antibody including atezolizumab, avelumab, pembrolizumab, or nivolumab. Only patients for whom the immediate preceding line of therapy was an ICI are allowed.
  • Measurable disease per RECIST v1.1
  • Evaluable IMDC risk score
  • Archival tumor specimen, and pretreatment tumor tissue from fresh biopsy at screening, if clinically feasible. Both archival and fresh samples are preferred.
  • KPS score of >=70
  • Recovery to baseline or Grade
  • Adequate hematologic and end-organ function
  • Negative HIV test at screening
  • Negative hepatitis B testing at screening
  • Negative hepatitis C virus (HCV) antibody test at screening, or positive HCV antibody test followed by a negative HCV RNA test at screening
  • For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraception and agreement to refrain from donating eggs
  • For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom, and agreement to refrain from donating sperm

Exclusion Criteria:

  • Treatment with anti-cancer therapy within 14 days prior to initiation of study treatment
  • Patients received cabozantinib at any time prior to screening
  • Patients who received more than one ICI treatment in the locally advanced or metastatic setting
  • Patients who received more than two prior lines of therapy in the locally advanced or metastatic setting
  • Patients who have received a mammalian target of rapamycin (mTOR) inhibitor in any setting
  • Symptomatic, untreated, or actively progressing CNS metastases
  • History of leptomeningeal disease
  • Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures
  • Uncontrolled or symptomatic hypercalcemia or symptomatic hypercalcemia requiring continued use of bisphosphonate therapy or denosumab
  • History of malignancy other than renal carcinoma within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death
  • Radiotherapy for RCC within 14 days prior to Day 1 of Cycle 1
  • Active tuberculosis
  • Major surgical procedure, other than for diagnosis, within 4 weeks prior to initiation of study treatment, or anticipation of need for a major surgical procedure during the study
  • Pregnancy or breastfeeding, or intention of becoming pregnant during study treatment or within 5 months after final dose of atezolizumab and 4 months after final dose of cabozantinib
  • Severe infection within 4 weeks prior to initiation of study treatment, including, but not limited to, hospitalization for complications of infection, bacteremia, or severe pneumonia, or any active infection that, in the opinion of the investigator, could impact patient safety
  • Pharmacologically uncompensated, symptomatic hypothyroidism
  • Uncontrolled hypertension defined as sustained blood pressure >150 mm Hg systolic or > 90 mm Hg diastolic despite optimal antihypertensive treatment
  • Significant cardiovascular disease (such as New York Heart Association Class II or greater cardiac disease, unstable arrhythmia, or unstable angina) within 3 months prior to initiation of study treatment
  • Significant vascular disease (e.g., aortic aneurysm or arterial dissection requiring surgical repair or recent peripheral arterial thrombosis) within 6 months prior to Day 1 of Cycle 1
  • History of congenital QT syndrome
  • History or presence of an abnormal ECG that is clinically significant in the investigator's opinion
  • Concomitant anticoagulation with coumarin agents (e.g., warfarin), direct thrombin inhibitor dabigatran, direct factor Xa inhibitor betrixaban, or platelet inhibitors (e.g. clopidogrel)
